Shimano ULTEGRA SL-BS78 - TECHNICAL Istruzioni operative

SI-6J60A

SL-BS78

Obtain and read the service instructions carefully

prior to installing the parts. Loose, worn, or damaged

parts may cause serious injury to the rider.

We strongly recommend only using genuine

Shimano replacement parts.

Read these Technical Service Instructions carefully,

and keep them in a safe place for later reference.

For smooth operation, use the specified outer casing

and bottom bracket cable guide.

Because the high cable resistance of a frame with

internal cable routing would impair the SIS function,

this type of frame should not be used.

The sliding surfaces of the inner cable and outer

casing should be greased before use.

The shifting lever can be installed to handlebars with

diameters of 19.0 – 22.0 mm.

Operation of the levers related to gear shifting

should be made only when the front chainwheel is

turning.

Parts are not guaranteed against natural wear or

deterioration resulting from normal use.

For any questions regarding methods of handling or

maintenance, please contact the place of purchase.

Do not turn the ring until the lever has been secured

to the body unit.

In order to realize the best performance, we recommend

that the following combination be used.

The illustration shows an explanation of the case

where the shifting lever is installed to drop handlebars.

Install the front lever in the same way.
